Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with embedded antenna devices in touch panels or display devices, compact design requirements often lead to degraded touch functions and radiation performance due to space constraints and interference with light movement.
Innovation Solution
The conductors for the antenna radiator are arranged between the pixels of the display device, preventing interference with light and allowing for a compact design by eliminating the need for a separate space for the antenna radiator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If antenna devices are embedded in touch panels to reduce mounting space, then device compactness is improved, but touch function performance deteriorates
Solution Approach 1:
The antenna device is merged with the touch panel structure by using the touch panel's conductive layers and structural components as part of the antenna system. The touch panel's front surface, conductive layers, and support structures are integrated to form the antenna radiator and feeding structures, eliminating the need for separate antenna mounting space while maintaining both touch and antenna functions.
Solution Approach 2:
The touch panel structure serves multiple functions: it acts as both the touch sensing interface and the antenna radiation structure. The conductive layers that enable touch functionality are also utilized as antenna feeding lines and radiator elements, allowing the same structural components to fulfill both touch panel and antenna device roles simultaneously.
2Volume of moving object
If antenna devices are embedded in display devices to reduce mounting space, then device compactness is improved, but light transmission quality deteriorates
Solution Approach 1:
The antenna conductors are arranged in the plane between pixels rather than extending vertically or blocking light paths. By positioning the antenna radiator conductors in the horizontal plane within the pixel structure, the design allows light to pass through vertically without significant obstruction, maintaining display quality while enabling antenna functionality.
Solution Approach 2:
The conductor arrangement is optimized locally within each pixel region to minimize light interference. The conductors are positioned and shaped to provide adequate radiation performance while being transparent or minimally obstructive to light transmission through the display pixels, creating local optimizations that balance both antenna and display functions.
3Area of moving object
If antenna area is reduced to meet compact design trends, then device slimness is improved, but radiation performance deteriorates
Solution Approach 1:
The antenna design utilizes parameter optimization including conductor width, length, spacing, and pattern geometry to achieve adequate radiation performance in a reduced area. By carefully adjusting these dimensional parameters and the electrical characteristics of the conductive layers, the antenna maintains functional performance despite the reduced overall area available in compact devices.
